How to use 'scp' to directly send my file to the target location via a gateway?

In my Linux computer, usually I login into the target location by SSH:

First, SSH to gateway ,

then, SSH to the target location

However, I cannot directly transmit file /Users/david/files/A in my computer to without logining by 'scp /Users/david/files/A '

How can I do this?

create a tunnel first: ssh -L 2222:yy.yy.yy.yy:22 , then you can scp with scp -P 2222 A fun@localhost.
